特别想在/etc/hosts不离开 Intellij 窗口的情况下进行编辑。在 Intellij 中处理某个任意项目时如何打开此文件？

从不懂JS的人开始：

for (var i=1; i<=5; i++) {
    setTimeout( function timer(){
        console.log( i );
    }, i*1000 );
}

给

但是像这样使用IIFE

for (var i=1; i<=5; i++) {
    (function(){
        var j = i;
        setTimeout( function timer(){
            console.log( j );
        }, j*1000 );
    })();
}

给

1

我的问题：为什么不

for (var i=1; i<=5; i++) {
    setTimeout( function timer(){
        var j = i;
        console.log( j );
    }, i*1000 );
}

要么

for (var i=1; …

我想使用本地Maven存储库（~/.m2/repository默认情况下）来查找boot生成的Clojure项目的依赖项。

我非常确定依赖项在存储库中：

$ ls ~/.m2/repository/ags799/boot-docker/0.0.0-7-gd5196b9-dirty/
_maven.repositories
boot-docker-0.0.0-7-gd5196b9-dirty.jar
boot-docker-0.0.0-7-gd5196b9-dirty.pom

我很确定我的项目正确地引用了依赖项。这是我的build.boot

(set-env! :dependencies `[[org.clojure/clojure ~(clojure-version)]
                          [ags799/boot-docker "0.0.0-7-gd5196b9-dirty.jar"]])

(task-options!
  pom {:project 'example
       :version "0.0.0"}
  aot {:namespace #{'example.core}}
  jar {:main 'example.core})

但是，当我运行时boot repl，我得到了：
